In the present embodiment, the piston ring 200 comprises at least two guide rings; each guide ring is in interference connection with the connecting rod assembly; the connecting rod assembly 300 reciprocates in the pump body 100 under the guidance of the guide ring. At least two of the guide rings may be equidistantly or randomly distributed on the inner sidewall of the pump body 100, and the shape of the guide rings may be the same or different, and the shape and arrangement of the guide rings are not limited in this application.
